hey, im making software for a client and i installed newest version of air on his winxp laptop and tried installing my app on his machine by opening the .air in airinstaller and got a "cant install app is damaged get another version from developer" (or something to that effect) and wen i try to install any air app with the badge it gives an error as well. ive searched around for an anwser and there seemsd to be others with this problem and it seemed like adobe was trying to stop it back in 08 and was wondering if anyone has a solution for this problem yet? i tried clearing the temp and i dont know if xp has "certifications" and if it does i dont know how to clear those.

uncheck the timestamp checkbox after clicking export release build .It may help if you are using flex 3 beta or flex 4 beta. Also try to remove external png files that you are packaging within your application.

ok ill give that a try and see if it works when i go out to see my client again on monday. the weird thing about the situation tho is that i cant install ANY air apps on his machine and 2 other machines running winxp ive been successful in installing my app (not to mention my mac aswell).
